Description

Detailed Description of the Invention The present invention automatically introduces the leading edge of a veneer veneer cut with a veneer lace and transported by an incoming conveyor to a take-up reel or bobbin, and winds it along its outer periphery. This invention relates to a veneer veneer winding device that can be attached and sequentially rolled up.

Conventionally, this type of work has been carried out by temporarily stopping the veneer lace, the veneer veneer conveyor 1 and the side drive roll 2, and manually winding the leading edge of the veneer veneer S onto the outer circumferential surface of the reel 3, as shown in Fig. 1. After winding, cutting was restarted, and winding was performed sequentially.

However, the veneer veneer S is transported at right angles to the fiber direction and has many cracks, so it is easily torn. The side drive roll 2 had to be temporarily stopped and the leading edge of the following veneer veneer S had to be manually wrapped around the outer circumferential surface again, which required manual labor each time and caused a significant drop in work efficiency.

In addition, curls occur in the narrow veneer veneer S, which is mainly cut at the initial and final stages of wood cutting, due to cracks on the back during cutting, and these are manually corrected each time before being rolled into the conventional machine. This not only reduces work efficiency but also takes time, making it virtually impossible to wind up the material at a rate that corresponds to the cutting speed.

Therefore, in reality, this kind of narrow veneer veneer S is not wound up, but is discharged outside the machine, stored, and then supplied to the next process, which requires extra manpower and storage space. Ta.

In addition, in recent years, proposals have been made in Japanese Patent Application Laid-Open No. 58-33403 and Japanese Patent Application Laid-open No. 57-9658 to automate the above-mentioned winding work, but the former winding method mainly uses a single core. The target is rectangular strip veneers that have been cut to size or a fixed length, and after being subjected to a tender treatment, two sets of endless strip winding conveyors are run in contact with the outer periphery of the wound ball. It is something. However, according to this method, not only is it necessary to reduce the cutting speed of the veneer lace due to the tendering process, but also the joint between the two sets of winding conveyors must be synchronously controlled as the number of spools increases. They must be stretched synchronously without any gaps, and if they are out of synchronization, the two sets of winding conveyors will not be in constant contact with the outer periphery of the bobbin, making it impossible to reliably wind the rectangular veneer. become unable. In addition, in the latter winding method, the veneer is wound around a reel at the upper rear end of the carry-in conveyor using a guide member. It will be press-fitted between the attached pulley and the take-up reel, and during this press-fitting, since the lower part has multiple pulleys, the veneer will drop slightly into the space between the pulleys, causing waves. It will look like a punch. This causes wrinkles in the veneer,
This may cause cracking and overlapping. Furthermore, this condition becomes more noticeable as the veneer becomes thinner.

In consideration of lyricism, the present invention is designed to be suspended between a belt groove provided around the side drive roll and a pressure pulley so as to be flush with the circumferential surface of the side drive roll, and at the same speed and in the same direction as the conveyor. By linking the veneer introduction member to a plurality of take-up guide belts that surround the lower side of the veneer veneer delivery side of the take-up reel, the leading edge of the veneer veneer is automatically removed. The veneer is introduced into the take-up reel or bobbin, and is further guided by a take-up guide member that wraps around the veneer veneer inlet from the veneer unloading side of the take-up reel through the upper surface of the outer periphery to the vicinity of the veneer inlet. The veneer veneer to be carried out of the machine is passed through a take-up reel, and the veneer veneer to be carried out of the machine is passed through a take-up reel, and a winding guide conveyor is linked to the veneer veneer delivery conveyor, so that the veneer can be wound in sequence along the outer circumference of the ball. It is constructed so that it can be carried outside.

Next, the action will be explained.

First, the processing of the veneer veneer S to be carried out of the machine before winding is started will be described.

The pedestal 15 is swung downward by the compressing fluid cylinder 19 to bring the carry-in conveyor 10 into a substantially horizontal state, and the sliding frame 42 is moved diagonally downward along the sliding guide 44.

Next, the pressure pulley 31 of the winding guide conveyor 36
is rotated by the pressurized fluid cylinder 35 to bring the winding guide belt 37 into a substantially horizontal state.

Furthermore, the veneer veneer discharge conveyor 25 is lowered by the discharge conveyor elevating fluid cylinder 22 to approximately the same height as the input conveyor 10.

Further, the sliding frame 42 is moved diagonally upward along the sliding guide 44 by the sliding frame elevating fluid cylinder 41 to widen the gap between the pressure roll 48 and the belt 14.

The upwardly curled veneer veneer S transferred by the carry-in conveyor 10 passes through the pressure roll 48 and the take-up reel 20, and is carried out of the machine by the take-up guide conveyor 36 and the veneer veneer carry-out conveyor 25. be done.

After being carried out of the machine, the drive of the carry-in conveyor 10 and the winding guide conveyor 36 is temporarily stopped, and during this time the pedestal 1
5. Return the sliding frame 42, winding guide conveyor 36, and veneer veneer discharge conveyor 25 to their respective winding states as described below.

That is, the sliding frame 42 is lowered by the sliding frame lifting/lowering cylinder 41.

Further, the terminal end of the gantry 15 is swung upward by a pressing fluid cylinder 17 with the pulley shaft 16 as a fulcrum, and presses the upper peripheral surface of the side drive roll 13 against the lower peripheral surface of the take-up reel 20, and the pressing roll 48 takes up the winding. It is biased toward the side of the reel 20.

Furthermore, the pressurizing body 56 is pressed into the pressurizing body pressing fluid cylinder 5.
7 to urge the side of the take-up reel 20,
A take-up guide member 59 is stretched along the outer circumferential upper surface of the take-up reel 20.

On the other hand, the pressure pulley 31 is connected to the pressurized fluid cylinder 35
The winding guide belt 37 is urged toward the outer circumferential side of the take-up reel 20 and stretched along the lower side of the outer circumferential side of the take-up reel 20 .

Further, the veneer veneer conveyor 25 is lifted by the conveyor elevating fluid cylinder 22, and the pressure roll 27 is disposed opposite to the side surface of the take-up reel 20 at an appropriate interval, and the veneer veneer introduction member 28 is connected to the guide body 30. It is stretched across the lower winding drum 29.

After returning to the winding state, the veneer veneer S transferred by the carry-in conveyor 10 is supplied to the take-up reel 20, and the leading edge of the veneer veneer S is wrapped around the lower side of the unloading side of the take-up reel 20. introduced by the take-up guide belt 37 and the take-up reel 20
The veneer veneer S is wound along the outer periphery of the take-up reel 20 by a winding guide member 59 that surrounds the veneer veneer S from the unloading side surface thereof to the vicinity of the introduction port through its upper surface.

During winding, as the diameter of the rolled ball increases, the rolling force of the rolled ball overcomes the pressing force of the pressurized fluid cylinder 17, so that the pedestal 15 is sequentially swung downward.

In addition, as the diameter of the winding ball increases, the first winding reel 2
Pressure pulley 31 that was energizing the center of the side of 0
is pushed forward by the winding ball, and then mount 1
5 is swung downward, the winding guide conveyor 36
Since the winding guide belt 37 is also swung downward, the winding range of the winding guide belt 37 sequentially moves downward.

On the other hand, the pressure roll 27, which was placed opposite the center of the side surface of the take-up reel 20 at an appropriate interval, is pressed against the rolled ball when the rolled ball reaches an appropriate diameter, for example, 190 mm to 200 mm, and as the rolled ball diameter increases, They are sequentially swung forward.

As the pedestal 15 swings downward and the pressure roll 27 swings forward, the veneer veneer introducing member 28 is sequentially unwound from the lower winding drum 29, and comes to wrap around the lower side of the outer circumferential surface of the rolled ball. .

In this case, the guide body 3 is arranged so that the amount of change in the ball biasing position of the pressure roll 27 is minimized, and the ball surrounding range of the veneer veneer introducing member 28 is sequentially expanded downward.
0, since the position of the lower winding drum 29 is set, the veneer veneer S is placed on the winding guide conveyor 36.
By the interlocking action of the veneer veneer introduction member 28 and the veneer veneer introducing member 28, the veneer veneer S of the winding ball is introduced to the vicinity of the center of the side surface on the delivery side.

Furthermore, as the roll diameter increases and the pedestal 15 swings downward, the pressure roll 48, which was initially urging the vicinity of the center of the veneer veneer S carry-in side side surface of the take-up reel 20, is moved to the sliding guide body 44. is moved downward along the line.

In addition, as the diameter of the winding ball increases, the pressure body 56, which was biased near the center of the side surface of the take-up reel 20 on the unloading side of the veneer veneer S by the pressure body pressing fluid cylinder 57, is pressed forward by the winding ball as the winding ball diameter increases. sway to.

As the pressure roll 48 is moved diagonally downward and the pressure body 56 is swung forward, the winding guide member 59 moves along the outer periphery of the rolled ball to the upper winding drum 60.
It is rewound sequentially from

In this case, the amount of change in the biasing position of the pressure body 56 is minimized, and the pressure roll 48 is configured to move obliquely downward as the pedestal 15 swings while biasing the rolled ball. The winding guide member 59 can constantly wrap the winding ball from the vicinity of the center of the veneer veneer S unloading side side surface to the vicinity of the veneer veneer S inlet through the outer periphery upper surface.

Therefore, the minimum diameter, that is, the diameter of the take-up reel 20,
For example, the leading edge of the winding guide conveyor 36 and the veneer veneer introducing member 28 automatically introduce the veneer veneer S to the vicinity of the center of the side surface on the delivery side by winding up the tip edge at an arbitrary diameter from 170 mm to an appropriate maximum diameter, for example 1000 mm. The veneer veneer S is further wrapped around the winding guide member 5.
9, it is wound smoothly and reliably along the outer periphery.

After the winding is completed, the pressurizing arm 58 is rotated clockwise in FIG.
Due to the contraction movement, the swing frame 51 is rotated clockwise about the sprocket shaft 52, thereby opening the winding guide member 59 that has been surrounding the winding ball from the top surface of the winding ball. 1
5. The veneer veneer delivery conveyor 25 and winding guide conveyor 36 are returned to their original state.

After unloading, the take-up reel 20 is supplied and the swing frame 5 is
1. The pressurizing body 56 is returned to its original state.

As described above, according to the present invention, the winding reel and the winding bobbin are wound around the veneer veneer discharge side side by the cooperation between the winding guide conveyor and the veneer veneer introducing member, and the winding reel and the winding bobbin are wrapped around the veneer veneer delivery side side by the winding guide conveyor and the veneer veneer introducing member. Since the veneer veneer is conveyed at high speed, the veneer veneer is transported at high speed without stopping the veneer race and the conveyor.
Its tip edge is automatically introduced at any diameter,
Wrapped along the outer circumference.

Further, the veneer guide belt and the carry-in conveyor, which rotate synchronously with the side drive roll, are suspended in a belt groove provided around the side drive roll so as to be flush with the circumferential surface of the side drive roll. Therefore, although there is a slight gap, the circumferential surface of the side drive roll becomes substantially flat, allowing smooth winding of the veneer. Furthermore, even if the diameter of the rolled ball increases, the winding guide member is sequentially rewound from the upper winding drum while being in contact with the outer periphery of the rolled ball by the pressurizing body that urges the side surface on the unloading side of the rolled ball. The outer periphery of the rolled ball is always automatically wrapped in cooperation with the winding guide conveyor.

Therefore, the manual work that conventionally involved stopping the carry-in conveyor and side drive rolls and manually wrapping the material has been completely eliminated.In addition, with conventional equipment, the material was transported outside the machine, stored, and then supplied to the next process. Automatic winding of narrow plywood veneers is also possible, which not only improves work efficiency but also saves on extra manpower and storage space.

Furthermore, when veneer veneers are carried out of the machine without being wound up on a take-up reel, for example, veneer veneers that are judged to be unsuitable for plywood production, which are mainly cut out at the initial stage of rough cutting, or the amount of winding For veneer veneers, etc., which are sent to the next process without being rolled up due to the small amount, the conveyance surfaces of the inlet conveyor, take-up conveyor, and veneer veneer discharge conveyor are the same, and if the pressure roll is raised, the veneers can be quickly transported out of the machine. Therefore, it is possible to ensure proper winding up or carrying out depending on the cut veneer veneer.
